A security label is a special type of label that indicates that a product or packaging has been tampered with, opened, or counterfeited. There are various types offering different levels of security, including void, invisible, perforated, fragile, and holographic labels. They are used to ensure product safety in the pharmaceutical, cosmetics, electronics, and food industries.
| Type | How does it work? | Area of Most Common Use |
|---|---|---|
| VOID Tag | It leaves a "VOID" or "OPENED" trace when removed. | Pharmaceutical, electronic, and document security. |
| Invisible Label | Contains hidden printing visible under UV light. | Luxury product, premium cosmetics |
| Perforated Labels | It breaks apart when lifted, it doesn't come out whole. | Food, beverage, and pharmaceutical caps. |
| Fragile Label | It crumbles when you try to peel it. | Electronics, warranty label |
| Hologram Label | Holographic pattern that changes color under light. | Pharmaceuticals, cosmetics, luxury goods |
| Security Tape | The packaging lid is sealed; it's obvious when it's opened. | Food, pharmaceutical, and cosmetic lids. |
VOID labels contain a hidden layer beneath the adhesive surface. When an attempt is made to remove the label from the packaging, this layer remains on the packaging, and "VOID," "OPENED," or a custom message appears. Even if the label is reapplied, the mark remains permanently visible. They are commonly used in pharmaceutical, electronics, and document security applications.
Invisible labels contain hidden printing that is not noticeable under normal light but becomes visible under UV light. The brand logo, serial number, or special pattern becomes visible under UV light. They are preferred for authenticity verification in luxury product and premium cosmetic brands.
Perforated labels contain specially cut holes on their surface. When an attempt is made to peel the label, it breaks apart along the perforations and does not come off in one piece. This prevents the label from being removed and reattached to another product. They are commonly used in food, beverage, and pharmaceutical cap sealing applications.
In the pharmaceutical industry, safety labeling is a legal requirement. While not mandatory in other sectors, it has become a strong choice for brand protection and consumer confidence.
VOID labels leave a mark on the packaging when removed, although the label itself may remain intact. Fragile labels, on the other hand, will disintegrate if someone tries to peel them off and cannot be reused.
Yes. Brand logos, serial numbers, barcodes, or QR codes can be printed on security labels. This provides both security and traceability.
Security tape is used to seal the packaging lid and is visible if opened. A security label, on the other hand, is affixed to the surface of the packaging and indicates tampering. Both can be used together. For detailed information, please see our security label page.

In the automotive industry, label selection is based on requirements such as high temperature resistance, chemical contact resistance, UV resistance, and longevity. Labels for lubricants, tires, batteries, and spare parts, unlike standard labels, must be produced with special materials and adhesives that are resistant to harsh conditions.
Material selection for detergent and cosmetic labels is determined by chemical resistance, moisture resistance, surface compatibility, and aesthetic requirements. Incorrect material selection can lead to label fading, peeling, or falling off the packaging. PP, PE, and polyester are the most commonly preferred materials.
Traceability on drug labels is ensured through technologies such as barcodes, QR codes, serial numbers, and data matrices. Tracking each unit of medication from production to consumption is a legal requirement. In Türkiye, under the Ministry of Health's Drug Tracking System (ITS), all medications are required to be marked with a QR code.
High-strength labels are a special type of label that maintains its durability for extended periods against extreme temperatures, humidity, chemical contact, and outdoor conditions. They are preferred in industrial equipment, automotive, machinery, and outdoor applications where standard labels are insufficient.
Multi-layer labels are a type of label that contains multiple layers, with the top layer being peel-off. They are used to present information in multiple languages on a single package, add detailed usage instructions, or create promotional content. They are commonly preferred in export packaging for the pharmaceutical, food, and cosmetics industries.
Hologram labels are security labels that feature a holographic effect that changes color in three dimensions under light. They provide visual verification against counterfeiting and product copying. They are used to guarantee product safety in the pharmaceutical, cosmetics, electronics, and premium food industries.
Adhesive label glue types are classified as hotmelt, acrylic, nonpermanent (removable), freezer-freeze, and re-adhesive glues. The correct glue selection is determined by the product's usage conditions, surface type, and temperature requirements.
Thermal labels are a type of label that contains a special heat-sensitive coating and can be printed with thermal printers without the need for ink. They are widely used in logistics, warehousing, shipping, and retail sectors for printing barcodes, QR codes, and variable data.
Metallic labels are a type of label made from special materials containing aluminum or metallic coatings, offering a bright and premium appearance. They are preferred in cosmetics, perfumes, olive oil, and industrial products to enhance brand value. Thanks to their waterproof structure, they are resistant to moisture and oil.
Roll labels are a type of adhesive label wound in a reel format for use in labeling machines. They are integrated into high-speed production lines with automated labeling systems. It is the most commonly used label format in the food, pharmaceutical, cosmetics, and logistics industries.
